Nd:YAG Laser Welding Systems

LaserStar offers a wide range of Nd:YAG laser welding systems which are fast, efficient, portable laser welding systems for high-speed laser welding applications. Ideal for non-contact welding processes which join two similar or certain dissimilar metals together. 

Cardiac pacemakers, defibrillators, guide wires, catheters, hearing aids, orthodontic appliances, prosthetics and surgical tools are just a few of our many successful medical device applications using laser welding and laser marking systems! 

LaserStar laser welding systems can produce both spot laser welds (single pulse) and seam laser welds (multi-pulse overlapping spots), including hermetically sound laser seams. 

FiberStar Laser Welding Workstations

FiberStar Laser Welding Workstations are designed with the needs of the precision micro-welding and micro-cutting industry in mind, providing a level of accuracy and consistency previously unavailable. This is made possible due to the unique capabilities of the fiber laser engine, including sub 0.5% pulse-to-pulse energy variation, +/-0.5% CW power stability over time, single-mode (TEM⁰⁰) beam quality and focused spot sizes down to 10μm. These features, coupled with close-loop power feedback, pulse profiling, high energy efficiency and no optical parts to align or calibrate, makes the FiberStar laser welding system an attractive laser engine for practical shop floor environments

Advantages of FiberStar Laser Welding Systems

• Fiber laser welding systems do not exhibit the shortcomings in output power, spot size and focal point variations caused by thermal effects on the glass rods of traditional YAG laser welders.

•  Fiber laser welders offer true welding consistency at all power levels, across all pulse sequences and during the entire lifetime of the laser. The laser parameters remain predictable and consistent. The reason for this is that the generation and transport of the laser beam to the work-piece takes place entirely within the confines of a single mode fiber. The beam shaping provided by this fiber neither degrades over time nor changes with laser power - this also makes the laser physically robust and stable, thus suitable for the most challenging of industrial environments.

• Additional advantages of fiber laser welders are the small spot size and high beam quality that translate to high irradiance at the focal plain. Workstations equipped with fiber laser welders can produce better results at lower power levels. The focused beam of energy consistently affects a very small area of metal, providing the benefit of very little heat generated around the weld point.

• High quality, precision laser welding can be performed extremely close (0.1mm) to the most complicated and intricate component parts.

•  Fiber laser welding system applications are not limited to just welding. Cutting of medical grade steels and wire end preparation for medical components are both effectively produced with the FiberStar Laser Welding Workstation.

• From an economics standpoint, the consistent and improved laser welding performance reduces scrap and generates faster production throughputs, resulting in a lower cost of ownership and improved laser up-times.

These financial and performance advantages mean that fiber laser technology is now frequently chosen as an upgrade over conventional flash-lamp pumped solid state lasers, or even DPSS laser technology in many other laser-based manufacturing segments. In addition, a small footprint and fast ROI open up markets that were previously out of reach for some laser welding applications.
 

Laser Marking and Engraving Systems

LaserStar’s laser marking and laser engraving systems are a fast and clean technology that is rapidly replacing older laser technologies.  Direct laser part marking has now become a common process in the medical device marketplace.  It offers a non-contact, abrasion-resistant, permanent laser mark onto almost any type of material.  

 High speed, high precision, micro-marking and/or engraving of part information, readable alpha-numerics, barcodes or Data-Matrix™, serial numbers, corporate logos, etc. are possible on a wide range of component parts.
